<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;"><a href="http://www.nasa.gov/home/index.html" rel="nofollow">NASA</a>'s Swift satellite has found evidence of the presence of a
previously unknown stellar-mass black hole in our Milky Way galaxy.<br />Named
Swift J1745-26 after the coordinates of its sky position, the nova is
located a few degrees from the centre of our galaxy towards the
constellation Sagittarius,

<span style="font-family: Arial,Helvetica,sans-serif;">While astronomers do not know its precise distance, they think the
object resides about 20,000 to 30,000 light-years away in the galaxy's
inner region.<br /><br /><img align="right" alt="Black Hole" src="http://www.hindustantimes.com/Images/HTEditImages/Images/black-hole-stars-1.jpg" />The
satellite detected a rising tide of high-energy X-rays from a source
toward the centre of Milky Way and the outburst, produced by a rare
X-ray nova, announced the presence of the black hole.<br /><br />"Bright
X-ray novae are so rare that they're essentially once-a-mission events
and this is the first one Swift has seen," said Neil Gehrels, the
mission's principal investigator, at <a href="http://www.nasa.gov/home/index.html">NASA's Goddard Space Flight Center</a>.<br /><br />"This is really something we've been waiting for," Gehrels said.<br /><br />An
X-ray nova is a short-lived X-ray source that appears suddenly, reaches
its emission peak in a few days and then fades out over a period of
months.<br /><br />The outburst arises when a torrent of stored gas suddenly
rushes toward one of the most compact objects known, either a neutron
star or a black hole.<br /><br />Ground-based observatories detected
infrared and radio emissions, but thick clouds of obscuring dust have
prevented astronomers from catching Swift J1745-26 in visible light.<br /><br />"The
pattern we're seeing is observed in X-ray novae where the central
object is a black hole. Once the X-rays fade away, we hope to measure
its mass and confirm its black hole status," said Boris Sbarufatti, an
astrophysicist at Brera Observatory in Milan, Italy.<br /><br />The black
hole must be a member of a low-mass X-ray binary (LMXB) system, which
includes a normal, Sun-like star. A stream of gas flows from the normal
star and enters into a storage disk around the black hole.<br /><br />In
most LMXBs, the gas in the disk spirals inward, heats up as it heads
toward the black hole, and produces a steady stream of X-rays.

<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">Moffett Field, California - Just in time for World Space Week, NASA
has released a new mobile application that challenges gamers to take on
the role of a space communications network manager and puts them in
charge of building a communications network to support scientific
missions.</span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">The educational application, "Space Communications and Navigation:
NetworKing," was developed at NASA's Ames Research Center in Moffett
Field, Calif., for the iPad and iPhone. NetworKing provides an
interactive, 3-D experience with an insider's perspective into how
mission controllers and scientists communicate with spacecraft and
satellites using the space, deep space and near Earth networks. <br /><br />"This
game introduces the complex world of space communications to gamers,"
said Barbara Adde, policy and strategic communications director for the
Space Communications and Navigation Division at NASA Headquarters in
Washington. "It gives players the opportunity to enjoy a challenging
game while absorbing the basic concepts of space communications. The
game provides an engaging way to increase interest in the areas of
science, technology, engineering and mathematics and opens minds to
potential careers in these fields." <br /><br />NetworKing allows players to
build increasingly large and complex communication networks to support
client satellites conducting scientific missions. Players who upgrade
their communication networks can acquire more complex clients, such as
the International Space Station and NASA's Hubble and Kepler space
telescopes. <br /><br />By providing insight into the complex world of
communications between astronauts, mission controllers, scientists and
satellites in real mission scenarios, the game is not only challenging,
but also entertaining. <br /><br />In addition to the mobile application,
NetworKing also is available free on the NASA 3-D Resources website.
Players can access the game on their web browsers or it can be
downloaded and run on PC or Macintosh operating systems. <br /><br />For links to download the app, download the game or play in a web browser, visit:</span></div>

<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">A private rocket successfully sent a capsule full of cargo zipping
toward the International Space Station in a first of its kind delivery
for NASA, but couldn't deliver on job No. 2: putting a commercial
satellite into the correct orbit. </span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">One of nine engines on <a href="http://www.nasa.gov/home/index.html">Space X company's Falcon 9 rocket</a> failed
Sunday 79 seconds after launch because of a pressure loss. The engine
didn't explode, but it did start a series of events that meant another
company's private satellite is not in the place it is needed. </span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">The main mission for the Falcon launch _ delivering half a ton of
science and food supplies toward the space station _ is still on track
with a docking of the cargo-laden Dragon capsule scheduled for
Wednesday. SpaceX on Monday said the ship's flight computer calculated a
new path to the station for the capsule. It is the first of a dozen
supply runs under a mega-contract with NASA. </span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">“Falcon 9 did exactly what it was designed to do,'' the
California based SpaceX said. “Like the Saturn V, which experienced
engine loss on two flights, Falcon 9 is designed to handle an engine out
situation and still complete its mission.''
</span></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">But not all of its mission. </span></div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">The original plan was for Falcon to fire its second stage engines
after Dragon left and then deploy an industrial communications
satellite into orbit for Orbcomm of Dulles, Virginia.
</span></div>
<div style="text-align: justify;">
<span style="font-family: Arial,Helvetica,sans-serif;">Because this is a new resupply ship for the space station, NASA
and its international partners had set detailed safety rules in advance
for Falcon, even though the engine failure was far from the station. And
those rules prevent SpaceX from firing its second stage engines,
Orbcomm said in a statement.

<span style="font-family: Arial,Helvetica,sans-serif;">One may think that participation with the <a href="http://nasa-information.blogspot.com/">International Space Station</a>
would be restricted to an exclusive club of high ranking officials and
agencies. In actuality, students, teachers and commercial companies have
also been taking advantage of the station's unique environment for
years. One of those commercial companies, Houston-based Odyssey Space Research, plans to bring the experience to the rest of us via our mobile devices!
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
International Space Station National Laboratory partner NanoRacks LLC has a collaboration with Odyssey and Apple.
This relationship enabled Odyssey to send two iPhone 4's to the space
station as part of the STS-135 mission on July 8, 2011. These phones are
just like the ones you can find at the store, but with certain
alterations to meet NASA flight certification standards. It took less
than a year to make the necessary changes and launch the devices to the
station.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
The iPhone 4 was selected for its mix of features, according to Odyssey
CEO Brian Rishikof. "It had a three-axis gyro, and accelerometer, a high
resolution camera and screen, and the means to manipulate the image. We
had done some projects in the past that used all those features, but of
course it was big, dedicated equipment and suddenly here it is in this
small little package," said Rishikof.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
The smartphones use the same software as their Earth counterparts and Odyssey used standard tools to develop a new app called </span><i style="font-family: Arial,Helvetica,sans-serif;">SpaceLab for iOS</i><span style="font-family: Arial,Helvetica,sans-serif;">,
which will enable the planned research aboard the station. The app is
also available for people to download to their own devices.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
These devices are part of an investigation called NanoRacks Smartphone,
which looks at how the phones will operate in space. The hope is to use
the compact hardware in future research studies and to augment crew
performance and productivity in operational activities. Currently there
are four separate experiments that will run on the smartphones via
SpaceLab for iOS.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
The first study is Limb Tracker, a navigation experiment using photos of
the Earth and image overlay manipulation to match the horizon to an arc
to give an estimate of altitude and off-axis angles. Next is the Sensor
Calibration or Sensor Cal experiment, which uses reference photos and
the three-axis gyro and accelerometer for calibration to improve
measurement accuracy. The State Acquisition or State Acq experiment also
uses photos, but this time to estimate spacecraft orbital parameters.
After the first three investigations are complete, the Lifecycle Flight
Instrumentation or LFI experiment will operate to track the impact of
radiation on the phones. To do this, the devices will monitor
radiation-induced single bit upsets, which are unintended changes in
memory location values.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
One of the other goals in sending the phones to the space station is to
engage the public. The SpaceLab for iOS app for users on the ground is
identical to the software that was downloaded onto the space devices
prior to launch. </span><br />
<br />
<span style="font-family: Arial,Helvetica,sans-serif;">According to Rishikof, there is a setting in the
application that indicates if the equipment is in microgravity or not.
The software operates differently to accommodate the presence of
gravity. "There are 200 million devices that run the operating system
and could potentially run the application," said Rishikof. "Which means
there are 200 million users out there that could get a sense of what it
does; a sense of what an experiment in space might look like; a sense of
participation."
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
The investigation is planned to run on the space station in the fall of
2011. The phones are not intended to have the same leisure appeal as
they do on Earth, however, given the lack of iTunes, games and Internet
or roaming connectivity. "People have asked me if we were loading games
on the phones for the crew. No, we did not want them to be distracted,
though certainly it would have been fun!" said Rishikof.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
Once the investigation completes, the smartphones will return to Earth
at the next opportunity. Scientists will then analyze the stored data to
better understand how the devices can be used for future research on
the space station and how the phones react to the space environment.
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
Rishikof hopes to be able to share some of the space data with SpaceLab
for iOS app users, as well. "We do not have a monopoly on good ideas and
hope users will suggest new and compelling things to add," commented
Rishikof. "It is not a game, there's no leveling or challenges, the
objective is to get data. It really just provides a way to see what's
going on and while we don’t expect tons of downloads, we do expect a lot
of interest. This would create an unusual opportunity for the entire
world to get a look at some space data and explore it on their handheld
device."
</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">
The NanoRacks Smartphone investigation is not the only phone-related
study to launch to the space station with STS-135. The Synchronized
Position Hold, Engage, Reorient, Experimental Satellites or SPHERES, which has been aboard station since 2006, will also use smartphones
to enhance the satellites' capabilities. While the two studies use
different hardware, the overall capabilities of these smartphones offer
bigger returns for research using a smaller package.

<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
PASADENA, Calif. -- The initial work of <a href="http://nasa-information.blogspot.com/">NASA</a>'s Mars rover Opportunity at
its new location on Mars shows surface compositional differences from
anything the robot has studied in its first 7.5 years of exploration. </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
Opportunity arrived three weeks ago at the rim of a 14-mile-wide
(22-kilometer-wide) crater named Endeavour. The first rock it examined
is flat-topped and about the size of a footstool. It was apparently
excavated by an impact that dug a crater the size of a tennis court into
the crater's rim. The rock was informally named "Tisdale 2." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
"This is different from any rock ever seen on Mars," said Steve Squyres,
principal investigator for Opportunity at Cornell University in Ithaca,
N.Y. "It has a composition similar to some volcanic rocks, but there's
much more zinc and bromine than we've typically seen. We are getting
confirmation that reaching Endeavour really has given us the equivalent
of a second landing site for Opportunity." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
The diversity of fragments in Tisdale 2 could be a prelude to other
minerals Opportunity might find at Endeavour. In the past two weeks,
researchers have used an instrument on the rover's robotic arm to
identify elements at several spots on Tisdale 2. Scientists have also
examined the rock using the rover's microscopic imager and multiple
filters of its panoramic camera. </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
Observations by Mars orbiters suggest that rock exposures on Endeavor's
rim date from early in Martian history and include clay minerals that
form in less-acidic wet conditions, possibly more favorable for life.
Discontinuous ridges are all that remains of the ancient crater's rim.
The ridge at the section of the rim where Opportunity arrived is named
"Cape York." A gap between Cape York and the next rim fragment to the
south is called "Botany Bay." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
"On the final traverses to Cape York, we saw ragged outcrops at Botany
Bay unlike anything Opportunity has seen so far, and a bench around the
edge of Cape York looks like sedimentary rock that's been cut and filled
with veins of material possibly delivered by water," said Ray Arvidson,
the rover's deputy principal investigator at Washington University in
St. Louis. "We made an explicit decision to examine ancient rocks of
Cape York first." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
The science team selected Endeavor as Opportunity's long-term
destination after the rover climbed out of Victoria crater three years
ago this week. The mission spent two years studying Victoria, which is
about one twenty-fifth as wide as Endeavor. Layers of bedrock exposed
at Victoria and other locations Opportunity has visited share a
sulfate-rich composition linked to an ancient era when acidic water was
present. Opportunity drove about 13 miles (21 kilometers) from Victoria
to reach Endeavor. It has driven 20.8 miles (33.5 kilometers) since
landing on Mars. </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
"We have a very senior rover in good health for having already worked 30
times longer than planned," said John Callas, project manager for
Opportunity at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
"However, at any time, we could lose a critical component on an
essential rover system, and the mission would be over. Or, we might
still be using this rover's capabilities beneficially for years. There
are miles of exciting geology to explore at Endeavour crater." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
Opportunity and its rover twin, Spirit, completed three-month prime
missions in April 2004 and continued working for years of extended
missions. Both have made important discoveries about wet environments on
ancient Mars that may have been favorable for supporting microbial
life. Spirit ended communications in March 2010. </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
"This is like having a brand new landing site for our veteran rover,"
said Dave Lavery, program executive for NASA's Mars Exploration Rovers
at NASA Headquarters in Washington. "It is a remarkable bonus that comes
from being able to rove on Mars with well-built hardware that lasts." </div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
<br /></div>
<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">
NASA will launch its next-generation Mars rover, Curiosity, between Nov.
25 and Dec. 18, 2011. It will land on Mars in August 2012. JPL, a
division of the California Institute of Technology in Pasadena, manages
the Mars Exploration Rover Project for <a href="http://nasa-information.blogspot.com/">NASA</a>'s Science Mission
Directorate in Washington.

<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">During its examination of Mars, the Viking 1 spacecraft returned images of Valles Marineris, a huge canyon system 5,000 km, or about 3,106 miles, long, whose connected chasma or valleys may have formed from a combination of erosional collapse and structural activity. This synthetic oblique view shows Ophir Chasma, the northern most one of the connected valleys of Valles Marineris. For scale, the large impact crater in lower right corner is about 18.5 miles, or 30 km, wide.<br />
<br />
Ophir Chasma is a large west-northwest-trending trough about 62 miles, or 100 km, wide. The Chasma is bordered by high-walled cliffs, most likely faults, that show spur-and-gully morphology and smooth sections. The walls have been dissected by landslides forming reentrants. The volume of the landslide debris is more than 1,000 times greater than that from the May 18, 1980, debris avalanche from Mount St. Helens. The longitudinal grooves seen in the foreground are thought to be due to differential shear and lateral spreading at high velocities. </div></div>Nasa Informationhttp://www.blogger.com/profile/16658545290139707354noreply@blogger.com0tag:blogger.com,1999:blog-8297034357860717924.post-20708511525012902352011-08-22T22:42:00.000-07:002011-08-22T22:42:36.137-07:00Discovering New Orbits with Kids in Micro-g<div dir="ltr" style="text-align: left;" trbidi="on"><div class="name_address" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><div class="promodatepress"><span class="bold"></span></div><div style="clear: both;"></div></div><div style="text-align: center;"><span class="img_comments_right" style="font-family: Arial,Helvetica,sans-serif;"><a href="http://nasa-information.blogspot.com/"><img align="Bottom" alt="Cady Coleman and Ron Garan measure the orbiting radius of a water droplet" border="0" height="170" src="http://www.nasa.gov/images/content/581512main_drop1_266.jpg" title="Cady Coleman and Ron Garan measure the orbiting radius of a water droplet" width="226" /></a> </span></div><div style="text-align: justify;"><br />

<span class="img_comments_right" style="font-family: Arial,Helvetica,sans-serif;"> </span><span style="font-family: Arial,Helvetica,sans-serif;"> Even simple scientific experiments can yield amazing results and add to the collective knowledge of the research community. Take the winning proposal for the most recent round of the </span>Kids in Micro-g competition, for example, which was designed by two 5th grade girls from Chabad Hebrew Academy in San Diego. Conducted in April 2011 on the International Space Station, this study, called "Attracting Water Drops," looked at static attraction in microgravity to reveal an exciting new understanding of physics in space. <br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Kids in Micro-g was a hands-on design challenge and part of <a href="http://nasa-information.blogspot.com/">NASA</a>'s </span>Teaching from Space<span style="font-family: Arial,Helvetica,sans-serif;"> education program. </span>Six finalists<span style="font-family: Arial,Helvetica,sans-serif;"> were selected in the 2011 Kids in Micro-g competition, earning the chance to have their proposed studies performed on the space station. The Attracting Water Drops experiment involved rubbing a piece of rubber tubing with a pair of nylon shorts to create a static charge. Then astronauts released a droplet of water close by and watched to see what happened. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Marilyn Sniffen, advanced placement science coordinator with Chabad Hebrew Academy, found out about the Kids in Micro-g competition while researching new challenges for her students online. Having previously participated with her classes in other NASA education challenges, she was aware of NASA as a resource to help foster a love of science in students. "I asked my current students if they would like to participate," said Sniffen. "There was no hesitation, as they immediately wanted to check out the list of supplies available for the physics tests that could be done aboard the space station." </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Students did their own companion study in the classroom to gain results for the investigation under the force of gravity here on Earth. They observed that a piece of charged rubber tubing held near a stream of running water caused the flow of water to bend toward the tubing. Students learned that the action of rubbing the tubing with nylon transferred negatively charged electrons to the tubing, creating a negative static charge. Since opposite charges attract to each other, and water molecules have a polarity with a positive end, the negatively charged tubing held near the water caused the positive end of the water to draw towards the tubing. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Astronauts Cady Coleman and Ron Garan performed the Attracting Water Droplets experiment aboard the station on April 23, 2011. You can view a video of the investigation being performed </span>here <span style="font-family: Arial,Helvetica,sans-serif;">. Their objective was to study the electrostatic interaction of the charged rubber tubing and water drops in microgravity. Students anticipated a greater attraction of the water droplet to the electrostatic charge than found on Earth. "Their hypothesis was that the results in space would be dramatically different than on Earth," commented Sniffen. "This is because the force of gravity on the water was greater than the force attraction to the static charge on the tube." </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> In addition to successfully proving the hypothesis, however, students and crew members were astonished to see the water droplet actually orbit the charged piece of tubing. "Look at that!" exclaimed Cady Coleman during the experiment on the space station. "It is going around our tubing. You would think it would keep sailing; in microgravity it would keep sailing, but it is coming back to our tubing and around." </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Sniffen echoed Coleman's surprise, as she detailed the student's expectations for the water droplets in space. "The students predicted that in micro-g, the drop would be free floating and that it could be 'pulled' around by the charged rubber tube without it falling to the ground. The actual experiment on the station showed they were able to pull the drop around in the air, but it also revealed a surprise we didn't predict. The droplet of water actually orbited the tube at about 6 cm! So our hypothesis was supported, but we learned something entirely new in the process. The kids were amazed, as were we!" said Sniffen. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> The school plans to repeat the Earth-bound portion of the experiment while showing the video of the study done on the space station to allow more students to share in the science next school year. "This kind of collaboration is really important for our students as they so often feel that what they are learning in school has no real connection to everyday life," comments Sniffen. "This program has allowed our students to make connections with real science and scientists, real discovery, and other students. It has inspired analytical thinking, creativity and communication for all our students." </span></div></div>Nasa Informationhttp://www.blogger.com/profile/16658545290139707354noreply@blogger.com2tag:blogger.com,1999:blog-8297034357860717924.post-22403917375817650682011-08-22T22:37:00.000-07:002011-08-22T22:37:41.580-07:00Hammin’ It Up<div dir="ltr" style="text-align: left;" trbidi="on"><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">A satellite with amateur radio capabilities and a student-designed experiment was released into orbit around Earth on Aug. 3, 2011, during a spacewalk outside the <a href="http://nasa-information.blogspot.com/">International Space Station</a>. The satellite is transmitting signals containing information that students around the world can access. <br />
<br />
The Amateur Radio on the International Space Station Satellite-1, or ARISSat-1, is a follow-on project to the unique SuitSat-1. SuitSat-1 was an amateur radio transmitter fitted into a surplus Russian Orlan spacesuit that was released from the station into space in 2006. SuitSat-1 transmitted for about two weeks and orbited Earth for seven months before burning up in Earth’s atmosphere. <br />
<br />
</div><div style="text-align: center;"><span class="img_comments_right"> <img align="Bottom" alt="ARISSat-1" border="0" height="170" src="http://www.nasa.gov/images/content/577528main_ARISSat_1-xltn.jpg" title="ARISSat-1" width="226" /> </span></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><span class="img_comments_right">The rectangular ARISSat-1 is covered by six solar panels that will charge the batteries in the satellite for about six months as it orbits Earth.

<br />
</span> Formerly known as SuitSat-2 and also called Radioskaf-V and Kedr by the project’s Russian partners, ARISSat-1 contains a student-designed experiment and other equipment that students can use to learn more about space and space exploration. ("Kedr," which is Russian for "Cedar" in English, was the call sign of Yuri Gagarin, a Russian cosmonaut and the first human in space.) <br />
<br />
ARISSat-1 is a project by the Radio Amateur Satellite Corporation, or AMSAT, and affiliated with the Amateur Radio on the International Space Station. ARISS is an education activity where space station astronauts and cosmonauts use amateur radio equipment aboard the space station to talk with students around the world. <br />
<br />
The development, launch and deployment of ARISSat-1 are being conducted as an educational mission with the support of the <a href="http://nasa-information.blogspot.com/">NASA</a> Office of Education’s ISS National Lab Education Project and RSC-Energia. It is the first of a series of educational satellites planned for deployment from the space station. Future satellites will carry additional student-built experiments, which will have data sent to the ground via amateur radio signals. <br />
<br />
AMSAT ARISSat-1 project manager Gould Smith said the educational mission of the project is to use the unique aspects of satellites and amateur radio transmissions to generate student interest in space, science, technology, engineering and mathematics. <br />
<br />
ARISSat-1 traveled to the space station in late January aboard a Russian Progress cargo vehicle and was released into space during a spacewalk by Russian cosmonauts Sergei Volkov and Alexander Samokutyaev. <br />
<br />
For ARISSat-1, the onboard experiment is from Kursk State Technical University in Kursk, Russia. The experiment is going to measure the vacuum in space at different altitudes as the satellite’s orbit decays, gathering 90 minutes of data each day and transmitting that data continuously back to Earth. By analyzing these data, student scientists can derive atmospheric density from <i>in situ</i> measurements. These data in turn can be used to better predict the orbital lifetime of ARISSat-1. <br />
<br />
</div><div style="text-align: center;"><span class="img_comments_right"> <img align="Bottom" alt="Close-up view of an experiment on ARISSat-1" border="0" height="170" src="http://www.nasa.gov/images/content/577529main_ARISSat_2-xltn.jpg" title="Close-up view of an experiment on ARISSat-1" width="226" /> </span></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><span class="img_comments_right">Aboard ARISSat-1 is an experiment that will measure the vacuum in space at different altitudes as the spacecraft de-orbits.

<br />
</span> Originally designed -- like its predecessor -- to fit inside an Orlan spacesuit, ARISSat-1 was redesigned when the expired spacesuit allocated for the project was disposed of sooner than AMSAT could use it. The redesign actually turned out to be a good move for the project, project managers said, because it allowed capabilities to be expanded. <br />
<br />
The rectangular spacecraft is covered by six solar panels that will charge the batteries in the satellite for about six months as it orbits Earth. Spoken telemetry values, with data such as temperature and battery life, are intended to promote science and mathematics education by encouraging schoolchildren to listen to the satellite, track its progress and plot the changes. AMSAT president Barry Baines said it’s a great opportunity for students to do actual science, by taking real-time, practical readings on a daily basis and plotting the changes. The telemetry data will be available live and over the Internet for schools and radio amateurs to study the operation and changes that the satellite experiences during its orbits around Earth. <br />
<br />
The project website provides free downloadable software that can be used to decode the data. "They can look at all the values, but you can also get the Russian experiment data at the same time and actually look at that every day," Baines said. "Plus, that data will be stored online, and they will be able to access it via the Internet to be able to go back and look at historical data or just use it in a lesson to actually take the real data and analyze it." <br />
<br />
"The most useful, exciting and effective element of learning in regards to this project is actually doing something hands-on and practical, rather than just sitting and listening to a lecture. If you can actually go out and collect the data and then do something with it, that’s a lesson that’s learned and understood at higher cognitive levels." <br />
<br />
In addition to data, the satellite will transmit 24 pre-recorded greetings in 15 different languages -- French, Spanish, German, English and Chinese, to name a few. More than half of the messages were recorded by schoolchildren, Smith said. "Most of them are really creative and interesting to listen to, especially male and female voices, and even kind of a little rap by the Dutch group. Also, most of them have a secret word at the end, and there’s a contest: If you can identify the secret word and send an e-mail, we’ll return an e-mail back to you with a little certificate." <br />
<br />
Attached to the inside of the satellite is a memory card containing images and documents from children around the world. A website has been set up to view the files on the card. There is also a contest to see who correctly copies the most Morse Code signals sent by ARISSat-1. The signals will consist of the call signs of all amateur radio operators who worked on the project. Additionally, still images of Earth will be transmitted from four cameras aboard the satellite. ARISSat-1 also will serve as an orbital communications relay station for use by amateur radio operators around the world. The ARISSat-1 website lists all of the ARISSat-1 contests and challenges. <br />
<br />
Helping with the project is NASA retiree Lou McFadin. McFadin has been closely involved with amateur radio and human spaceflight through the Shuttle Amateur Radio Experiment, or SAREX, project, beginning with astronaut Owen Garriott’s first amateur radio communications on the STS-9 shuttle mission in 1983. McFadin is the ARISS hardware manager and has worked with the development of the ARISSat-1 hardware since the start of the project. <br />
<br />
"I think if they (students) do the telemetry decode," McFadin said, "there’s a lot of opportunity for learning there. It has solar panel temperatures; it has solar panel data; it has battery voltage and all kinds of information there about what’s going on in the satellite. That kind of learning really connects to our goal of getting children and all Americans interested in space. That’s a big part of what we wanted to do." <br />
<br />
</div><div style="text-align: center;"><span class="img_comments_right"> <a href="http://nasa-information.blogspot.com/"><img align="Bottom" alt="A free-floating spacesuit and the curve of Earth" border="0" height="170" src="http://www.nasa.gov/images/content/577530main_ARISSat_3-xltn.jpg" title="A free-floating spacesuit and the curve of Earth" width="226" /></a> </span></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><span class="img_comments_right">SuitSat-1 in orbit after its release from the International Space Station during Expedition 12.

</span> ARISSat-1 also will serve as a technology demonstration. "For AMSAT, it certainly was a way to try out some new ideas -- how to build the structure for the dynamics of the satellite itself, it’s a new power system, it’s a new transponder system we’ve not tried before, it’s the first time we’ve flown a software-defined transponder, and it’s paving the path for the future for us," Smith said. <br />
<br />
McFadin said the software-defined transponder was the key to how they were able to design a satellite to do so many things at once. "It’s an FM transmitter, it’s a transponder, it’s a telemetry transmitter, and Morse code transmitter, all done with one system, all simultaneously," McFadin said. "We’ve never been able to do that before." <br />
<br />
This was AMSAT’s second opportunity to release a satellite from the International Space Station, and Smith said they hope to continue the project with future spacecraft and more student-designed experiments. "It’s not any harder to build four of something than it is to build one, hardly. So we built four space frames, five actually, one for the prototype, and we built four flight versions," Smith said. "So it’ll be easy to do this again." <br />
<br />
Mark Severance, manager for the ISS National Laboratory Education Project, sees ARISSat-1 as an important flight test for future educational satellites. "Future ARISSats will carry at least four student-designed and -built experiments," Severance noted. "This will give students the opportunity to go hands-on and build actual spaceflight experiment hardware. Furthermore, they can track the satellite using off-the-shelf amateur radio hardware and obtain the data from their experiment directly from their own ground station. In this manner, ARISSat can provide an 'end-to-end' space mission experience for participating students." <br />
<br />
NASA's Office of Education's ISS National Laboratory Project will sponsor future ARISSats. The project provides hands-on opportunities for elementary, secondary and university students, as well as lifelong learners, to participate in the space station mission. The ARISS school contact activity is supported by the ISS National Laboratory Project as well as the Teaching From Space Office at NASA's Johnson Space Center in Houston. Teaching From Space facilitates education opportunities like ARISS that use the unique environment of space to increase student interest in science, technology, engineering and mathematics. <br />

NASA's space shuttle fleet began setting records with its first launch on April 12, 1981 and continued to set high marks of achievement and endurance through 30 years of missions. Starting with Columbia and continuing with Challenger, Discovery, Atlantis and Endeavour, the spacecraft has carried people into orbit repeatedly, launched, recovered and repaired satellites, conducted cutting-edge research and built the largest structure in space, the International Space Station. The final space shuttle mission, STS-135, ended July 21, 2011 when Atlantis rolled to a stop at its home port, NASA's Kennedy Space Center in Florida.<br />
<br />
As humanity's first reusable spacecraft, the space shuttle pushed the bounds of discovery ever farther, requiring not only advanced technologies but the tremendous effort of a vast workforce. Thousands of civil servants and contractors throughout <a href="http://nasa-information.blogspot.com/">NASA</a>'s field centers and across the nation have demonstrated an unwavering commitment to mission success and the greater goal of space exploration.<br />

We got some air in that system a little while ago and it needs to basically purge itself out over the course of processing. So we think, because everything looks fine in the system, we think it's just working its way out of the system. So we stopped the urine processing for the time being and we're using the toilet basically in stand-alone mode right now."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Flight controllers likely will resume urine processing Wednesday but "not while the crew is doing EVA support,:" McMillan said. "They'll be using the robotics work station in the cupola, which is in the vicinity of the toilet, so we don't really want to be making a smell while they're working in there."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Today's spacewalk is the first during a shuttle visit that will be carried out by <a href="http://nasa-information.blogspot.com/">space station </a>personnel. Because of a short training flow and a requirement to launch Atlantis with a reduced crew of four, "we wanted to off load the training tasks on the shuttle crew and sort of level the load," lead station Flight Director Chris Edelen said before launch. "So we took advantage of the EVA experience of Mike Fossum and Ron Garan. They've actually done three spacewalks together on previous shuttle missions (and they) were able to get up to speed very quickly on this EVA."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Fossum has 42 hours and one minute of EVA time in his previous six spacewalks while Garan has 20 hours and 32 minutes of EVA experience.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Photos: <a href="http://nasa-information.blogspot.com/">NASA</a>'s final shuttle flight</span><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Photos: The storied career of Atlantis</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Returning the failed ammonia pump module is a high priority objective for NASA. The space station is equipped with two coolant loops that circulate ammonia through huge radiators to get rid of the heat generated by the space station's electrical systems. Last July 30, the pump in one coolant loop failed, forcing the crew to implement an emergency powerdown.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"I remember it because I was on console when it failed," Edelen said. "It was one of those moments where on a quiet Saturday and the crew's off duty and getting ready to go to bed and everything's going real well and it all changed in a second when that pump module failed. All the caution and warnings started going off and the crew had to very quickly scramble to reconfigure the systems and power down some of the systems in order to keep the station limping along on one remaining cooling loop.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"That was a major failure in the history of the space station program, the first major failure that required (U.S.) spacewalks without a shuttle present to fix a problem."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Over the course of three spacewalks, the pump module was successfully replaced by a pre-positioned spare. But the coolant system is critical to the station's long-term health and engineers want to find out what went wrong in the pump that failed. After troubleshooting, engineers plan to repair the pump and re-launch it aboard a Japanese cargo ship.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">After mounting the pump module in Atlantis' payload bay, Fossum and Garan plan to move an experimental robotic refueling apparatus from the shuttle to a storage platform used by the Canadian Special Purpose Dexterous Manipulator, or SPDM, a robot arm extension also known as DEXTRE.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"We are taking up a payload, it's called the robotics refueling module, this is to demonstrate a capability for the Special Purpose Dexterous Manipulator, which hasn't seen a whole lot of use on the International Space Station to date, but we hope to turn that all around with this payload," said shuttle commander Christopher Ferguson.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"I've kind of likened it to a Fisher-Price play toy for a robot. And I don't mean that in a negative sense, it is really an opportunity for the SPDM to get in there and use several different tools and prove the capability to do something extremely novel, and that is to refuel satellites in orbit that were never designed to be refueled.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"So the manipulator will actually go in and pick up special cutter tools and cut safety wire, it has a drill that can actually drill into a fuel tank so there's some very unique capabilities that will be demonstrated using this. What capability will robots provide to us in the future? To think about going out there and perhaps grappling a satellite that was never designed to be refueled ... and refill it and use it for an additional five or 10 years is a dramatic example of how robotics can modify what we're doing in space."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Along with moving the pump module to Atlantis and installing the robotics refueling kit on the station, Fossum plans to inspect a robot arm mounting fixture on the Russian Zarya module to re-position a grounding wire that appears to be caught in an access door. Both spacewalkers then will install a thermal shield over an unused docking port attached to Tranquility before heading back to the Quest airlock.</span></div>Nasa Informationhttp://www.blogger.com/profile/16658545290139707354noreply@blogger.com0tag:blogger.com,1999:blog-8297034357860717924.post-30369954081404271442011-07-13T23:13:00.000-07:002011-07-13T23:13:32.556-07:00The Last Space Shuttle Mission: Flight Day 6<div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><i>When <a href="http://nasa-information.blogspot.com/">Space Shuttle Atlantis</a> left Launch Pad 39A at the Kennedy Space Center on Friday, July 8, it marked the final liftoff for the long-running Space Shuttle Program, which has dominated NASA's manned operations for the past four decades. Over a 12-day mission (since extended to 13 days), the four-person crew on <a href="http://nasa-information.blogspot.com/">STS-135</a> will haul the Multi-Purpose Logistics Module (MPLM) Raffaello and a Lightweight Multi-Purpose Carrier (LMC) to the International Space Station.

</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">After a long day -- flight engineers Mike Fossum and Ron Garan completed a spacewalk that lasted more than six hours -- the NASA crew onboard Space Shuttle Atlantis had an early night on flight day 5. For the best, as the morning wakeup song -- Elton John's "Rocket Man" -- came at 2:29 a.m. EDT this morning. Once awake, the astronauts were greeted with a special message from Sir Elton John himself: "Good morning, Atlantis, this is Elton John," he said in a recording. "We wish you much success on your mission. A huge thank you to all the men and women at <a href="http://nasa-information.blogspot.com/">NASA</a> who worked on the shuttle for the last three decades."</div><div style="font-family: Arial,Helvetica,sans-serif;"> </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><i>Story continues after the gallery, which will be updated as the mission wears on.</i></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><i> </i> <img alt="The Final Spacewalk" class="galleryFeatureImage" height="480" src="http://cdn.theatlantic.com/static/easel/images/galleries/050532_569949main_image_2004_800-600.jpg" title="The Final Spacewalk" width="640" /><a class="galleryFeature" href="http://www.theatlantic.com/technology/archive/2011/07/the-last-space-shuttle-mission-flight-day-6/241866/#"> </a></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">The message from Sir John was a good way to get the crew ready for a long day of ... moving, basically.

</div><div class="Text-TextBody HoustonText" id="id2422790" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">Those may be the sentiments of many of the Houston space-industry workers, past and present, traveling in droves to Florida this week to watch the beginning of the end of <a href="http://nasa-information.blogspot.com/">NASA</a>'s space shuttle era, but they are going anyway.</div><div class="Text-TextBody HoustonText" id="id2422790" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div class="Text-TextBody HoustonText" id="id2422796" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">"In some ways, it's just sad to see it end," said Lisa Reed, 50, who worked for nearly 15 years at NASA before leaving to join a private consulting firm.

</div><div class="Text-TextBody HoustonText" id="id2420284" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">Though bittersweet, buzz about the final launch, scheduled for Friday, swept over Johnson Space Center in recent weeks as workers tried to secure coveted spaces on the NASA causeway at Cape Canaveral and planned flights, road trips and hotel stays to be a part of the historic day.</div><div style="font-family: Arial,Helvetica,sans-serif;"> </div><h3 class="Text-TextSubhed BoldCond PoynterAgateZero" id="id2420314" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">Bus space sells out</h3><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> </div><div class="Text-TextBody HoustonText" id="id2426874" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">NASA, after noticing ballooning interest among its workers in seeing the final shuttle launches, began organizing charter buses, accommodations and a designated viewing area to help workers travel and watch the start of the final missions, said Lisa Rasco, who coordinated the travel program for <a href="http://nasa-information.blogspot.com/">NASA</a>.</div><div class="Text-TextBody HoustonText" id="id2426874" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div class="Text-TextBody HoustonText" id="id2426882" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">Spaces on the buses for this week's launch sold out several weeks ago, Rasco said. The buses set out on the 18-hour journey Wednesday. A total of 130 people had reserved bus or hotel bookings through the NASA service, she said. Thousands of other workers are flying on their own, driving and planning their own stays before meeting at a Kennedy Space Center recreation facility that can accommodate 10,000 viewers. That area is expected to be filled with NASA workers and their families, she said.</div><div class="Text-TextBody HoustonText" id="id2426882" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div class="Text-TextBody HoustonText" id="id2426892" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> The final shuttle launch was a milestone that David Rose, 44, couldn't miss. A Florida native who worked at Johnson Space Center for 18 years before leaving and joining an engineering consulting firm, Rose helped train astronauts and has seen more than a dozen shuttle launches. </div><div class="Text-TextBody HoustonText" id="id2426900" style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">His life has been connected and inspired by the space program and industry, with him traveling to California in 2005 to see the first private spacecraft launch out of the atmosphere.

The mission, called Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer, or OSIRIS-REx, will be the first U.S. mission to carry samples from an asteroid back to Earth.<br />
<br />
"This is a critical step in meeting the objectives outlined by President Obama to extend our reach beyond low-Earth orbit and explore into deep space," said <a href="http://nasa-information.blogspot.com/">NASA Administrator</a> Charlie Bolden. "It’s robotic missions like these that will pave the way for future human space missions to an asteroid and other deep space destinations." </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="text-align: justify;"><span style="font-family: Arial,Helvetica,sans-serif;">NASA selected OSIRIS-REx after reviewing three concept study reports for new scientific missions, which also included a sample return mission from the far side of the Moon and a mission to the surface of Venus.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Asteroids are leftovers formed from the cloud of gas and dust -- the solar nebula -- that collapsed to form our sun and the planets about 4.5 billion years ago. As such, they contain the original material from the solar nebula, which can tell us about the conditions of our solar system's birth.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /> </div><div style="text-align: center;"><span class="img_comments_right" style="font-family: Arial,Helvetica,sans-serif;"> <img align="Bottom" alt="conceptual image of OSIRIS-REx" border="0" height="271" src="http://www.nasa.gov/images/content/552551main1_OSIRIS_Cover_Image-226x271.jpg" title="conceptual image of OSIRIS-REx" width="226" /> </span></div><div style="text-align: justify;"><br />

Once within three miles of the asteroid, the spacecraft will begin six months of comprehensive surface mapping. The science team then will pick a location from where the spacecraft's arm will take a sample. The spacecraft gradually will move closer to the site, and the arm will extend to collect more than two ounces of material for return to Earth in 2023. The mission, excluding the launch vehicle, is expected to cost approximately $800 million.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> The sample will be stored in a capsule that will land at Utah's Test and Training Range in 2023. The capsule's design will be similar to that used by NASA's Stardust spacecraft, which returned the world's first comet particles from comet Wild 2 in 2006. The OSIRIS-REx sample capsule will be taken to NASA's Johnson Space Center in Houston. The material will be removed and delivered to a dedicated research facility following stringent planetary protection protocol. Precise analysis will be performed that cannot be duplicated by spacecraft-based instruments.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> RQ36 is approximately 1,900 feet in diameter or roughly the size of five football fields. The asteroid, little altered over time, is likely to represent a snapshot of our solar system's infancy. The asteroid also is likely rich in carbon, a key element in the organic molecules necessary for life. Organic molecules have been found in meteorite and comet samples, indicating some of life's ingredients can be created in space. Scientists want to see if they also are present on RQ36. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> "This asteroid is a time capsule from the birth of our solar system and ushers in a new era of planetary exploration," said Jim Green, director, <a href="http://nasa-information.blogspot.com/">NASA</a>'s Planetary Science Division in Washington. "The knowledge from the mission also will help us to develop methods to better track the orbits of asteroids."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> The mission will accurately measure the "Yarkovsky effect" for the first time. The effect is a small push caused by the sun on an asteroid, as it absorbs sunlight and re-emits that energy as heat. The small push adds up over time, but it is uneven due to an asteroid's shape, wobble, surface composition and rotation. For scientists to predict an Earth-approaching asteroid's path, they must understand how the effect will change its orbit. OSIRIS-REx will help refine RQ36's orbit to ascertain its trajectory and devise future strategies to mitigate possible Earth impacts from celestial objects. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Michael Drake of the University of Arizona in Tucson is the mission's principal investigator. NASA's Goddard Space Flight Center in Greenbelt, Md., will provide overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space Systems in Denver will build the spacecraft. The OSIRIS-REx payload includes instruments from the University of Arizona, Goddard, Arizona State University in Tempe and the Canadian Space Agency. NASA’s Ames Research Center at Moffett Field, Calif., the Langley Research Center in Hampton Va., and the Jet Propulsion Laboratory in Pasadena, Calif., also are involved. The science team is composed of numerous researchers from universities, private and government agencies.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> This is the third mission in <a href="http://nasa-information.blogspot.com/">NASA</a>'s New Frontiers Program. The first, New Horizons, was launched in 2006. It will fly by the Pluto-Charon system in July 2015, then target another Kuiper Belt object for study. The second mission, Juno, will launch in August to become the first spacecraft to orbit Jupiter from pole to pole and study the giant planet's atmosphere and interior. NASA's Marshall Space Flight Center in Huntsville, Ala., manages New Frontiers for the agency's Science Mission Directorate in Washington. </span></div></div>Nasa Informationhttp://www.blogger.com/profile/16658545290139707354noreply@blogger.com0tag:blogger.com,1999:blog-8297034357860717924.post-56436566658525704062011-05-23T00:06:00.000-07:002011-05-23T00:06:43.803-07:00Caterpillar Inc. Participates in NASA's Second Annual Lunabotics Mining Competition<div dir="ltr" style="text-align: left;" trbidi="on"><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><b>Caterpillar promotes education and technology at international collegiate event</b><br />
<br />
Showcasing its world-class technology leadership, Caterpillar Inc. (NYSE: CAT) is supporting the NASA Lunabotics Mining Competition at the <a href="http://nasa-information.blogspot.com/">Kennedy Space Center</a>, Cape Canaveral, Florida. The event, May 26-28, is designed to engage and retain college students in the areas of science, technology, engineering and mathematics (STEM). For complete coverage, follow the competition on Twitter @CaterpillarInc. or #lmc2011.<br />
<br />
Tana Utley, Caterpillar Vice President and Chief Technology Officer, will be a keynote speaker during the opening ceremonies of the three-day event. "Educational outreach has been an important part of our collaboration with <a href="http://nasa-information.blogspot.com/">NASA</a>, and we look forward to continuing this focus during the Lunabotics Mining Competition," said Utley. "The technologies produced at the competition could one day be used in mine and work sites. What better way to enhance jobsite safety and efficiency than to design autonomous solutions."<br />
<br />
Participants in the competition will design and build autonomous systems that could be used for future lunar exploration. Teams will test their designs in a head-to-head challenge to see which machine can excavate the most simulated lunar "dirt" over a specific timeframe. "Caterpillar has a long history of supporting educational opportunities that promote the STEM areas," said Eric Reiners, Caterpillar Automation Manager, who is lending his expertise as a judge at the event. "We need to encourage technology, innovation and ingenuity to students of all ages. The development of autonomous systems will ultimately help our global customers boost safety, efficiency and increase profitability."<br />
<br />
Currently, there are 45 graduate and undergraduate student teams enrolled in the competition from various parts of the world. That number has more than doubled from last year's event. Caterpillar will have a 287C semi-autonomous Multi Terrain Loader (MTL) on display to showcase the technologies Caterpillar and <a href="http://nasa-information.blogspot.com/">NASA</a> are developing.<br />

style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">The station then will rotate 130 degrees in an unusual sideways pose that offers a good view of the station, Endeavour, and two cargo ships flown by Russia and Europe.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Italian astronaut Paolo Nespoli will climb temporarily into the windowed Soyuz module — a part of the craft that burns up during re-entry — and begin taking pictures and video of the shuttle and station floating 220 miles above the planet.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Nespoli will have about five minutes to take in the unique view before Soyuz thrusters fire to separate the spacecraft from the station and put Kondratyev, Nespoli and American Cady Coleman en route to a landing in Kazakhstan late Monday night.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">It sounds simple enough, but the whole process involves risks that took years to gain acceptance.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"There's been a lot of work by a whole lot of teams to make sure this is really a good thing to be doing, but folks are very comfortable with the plan," Courtenay McMillan, a station flight director, said of the photo opportunity.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"Now, instead of a unique configuration, we have more of what I term more of a unique opportunity," Todd said since not every vehicle would be represented in the picture.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">The opportunity arose when shuttle and station program leaders approved what is known as "dual docked operations."</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">In the past, vehicles coming and going from the station were conflicts for a shuttle mission to avoid.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Another showstopper could be coordinating shuttle and Soyuz crew schedules so each gets enough rest and can execute their separate missions without interference.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">In this case, engineers determined there was acceptable rocket fuel plume risk , and the schedules could be managed.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">But the photo opportunity presented additional challenges.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">The Soyuz will back away much like it always does, but at a slightly higher angle to make sure the sun doesn't blind Kondratyev while he manually keeps the spacecraft hovering behind the station for an extended period.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">The station had to figure out a pose that ensured good lighting, and flying in any new position, even for half an orbit, requires verification that systems won't be exposed to harmful temperatures.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">The photo orientation is "different enough from what we usually fly that it is outside what we know about, so folks had to go off and do the math and figure out what the problems would be," McMillan said.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">After taking the pictures, Nespoli will return to his seat in the crew module and seal the hatch. The crew module separates from two others and is the only part of the ship that survives atmospheric re-entry.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">But the Soyuz won't be able to immediately return to its port if there is trouble sealing the hatch, which normally is closed prior to undocking. The maneuver hasn't been studied enough to know it can be done safely.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Managers say a hatch problem is highly unlikely, the Soyuz has backup landing opportunities through Tuesday and managers would come up with a solution if necessary.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"We would get there," said Derek Hassmann, the lead flight director for Endeavour's visit to the station.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">Plans continue for another round of photos to be taken during the final shuttle flight. But that could be dropped if Monday's operation produces the desired imagery, which could be released within days.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">If the effort succeeds, Todd said he hopes the photos give future generations an appreciation for the feat represented by the station, which couldn't have been built without the <a href="http://nasa-information.blogspot.com/">shuttle</a>.</span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;">"So if we're ever to end up in the future somewhere in a book, it would be great to have the space shuttle represented there with us, as well as all the other international partners," he said.</span> </div></div>Nasa Informationhttp://www.blogger.com/profile/16658545290139707354noreply@blogger.com0tag:blogger.com,1999:blog-8297034357860717924.post-25845117554092688182011-05-22T23:35:00.000-07:002011-05-22T23:35:23.428-07:00Mars Rover Driving Leaves Distinctive Tracks<div dir="ltr" style="text-align: left;" trbidi="on"><div class="name_address" style="text-align: justify;"><br />

</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><span class="img_comments_right">A dance-step pattern is visible in the wheel tracks near the left edge of this scene recorded by the navigation camera on NASA's Mars Exploration Rover Opportunity during the 2,554th Martian day, or sol, of the rover's work on Mars (April 1, 2011). Image credit: NASA/JPL-Caltech <br />
<a href="http://www.nasa.gov/mission_pages/mer/multimedia/gallery/pia14129.html"></a></span></div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><span class="img_comments_right"> </span> </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> When <a href="http://nasa-information.blogspot.com/">NASA</a>'s Opportunity Mars rover uses an onboard navigation capability during backward drives, it leaves a distinctive pattern in the wheel tracks visible on the Martian ground. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> The pattern appears in an image posted at http://photojournal.jpl.nasa.gov/catalog/PIA14129 . </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> The rover team routinely commands Opportunity to drive backward as a precaution for extending the life of the rover's right-front wheel, which has been drawing more electrical current than the other five wheels. Rover drivers can command the rover to check for potential hazards in the drive direction, whether the rover is driving backward or forward. In that autonomous navigation mode, the rover pauses frequently, views the ground with the navigation camera on its mast, analyzes the stereo images, and makes a decision about proceeding. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> When the drive is backward, the drive-direction view from the navigation camera is partially blocked by an antenna in the middle of the rover. Therefore, at each pause to check for hazards, the rover pivots slightly to the side to get a clear view. If it sees no hazard, it turns back to the direction it was going and continues the drive for about another 4 feet (1.2 meters) before checking again. This set of activities leaves tracks showing the slight turnout on a rhythmically repeated basis, like a dance step. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Opportunity has driven more than 1.6 miles (about 2.6 kilometers) since leaving "Santa Maria" crater in late March and resuming a long-term trek toward the much larger Endeavour crater. Opportunity has now driven more than 18 miles (29 kilometers) on Mars. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Opportunity and its twin rover, Spirit, completed their three-month prime missions on Mars in April 2004. Both rovers continued in years of bonus, extended missions. Both have made important discoveries about wet environments on ancient Mars that may have been favorable for supporting microbial life. Spirit has not communicated with Earth since March 2010. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />

Johnson on Facebook and follow the match there or on Twitter. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Chamitoff and Johnson launched on a mission to the International Space Station on Monday, and have only two weeks to complete this match, so the action should be as fast and furious as the busy mission to deliver the Alpha Magnetic Spectrometer allows. They’re teaming up for this chess match challenge to the people of Earth. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> NASA and the U.S. Chess Federation (USCF) hosted the first Earth vs. <a href="http://nasa-information.blogspot.com/">space</a> match in 2008 when Chamitoff lived aboard the International Space Station. The public won that match thanks to help from chess champions at Stevenson Elementary School in Bellevue, Wash. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> "Chess is a great game that challenges the mind and helps young people develop critical thinking skills that will serve them well in math, science, and all aspects of their future careers," Chamitoff said. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> He and Johnson will play the game during their 14-day <a href="http://nasa-information.blogspot.com/">space shuttle flight</a> to the International Space Station. The USCF will facilitate the match on its website at: </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /> <a href="http://www.uschess.org/nasa2011/" style="font-family: Arial,Helvetica,sans-serif;"></a><span style="font-family: Arial,Helvetica,sans-serif;"> At the site, the public can suggest or vote on a chess move. The USCF will decide how to respond to the astronauts' moves. NASA and USCF will use Twitter and Facebook to notify participants about the status of the game and when to vote on moves. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> Chamitoff, who will conduct two spacewalks during the shuttle mission, is a chess aficionado. He took a chess set when he launched to the space station in May 2008, and brought it back when he returned home in November 2008. He will be taking a different chess set for this trip. </span><br style="font-family: Arial,Helvetica,sans-serif;" /><br style="font-family: Arial,Helvetica,sans-serif;" /><span style="font-family: Arial,Helvetica,sans-serif;"> "We hope to do better in this Earth vs. space match," Chamitoff said.

<br />
</span> </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> PASADENA, Calif. – Final preparations are under way for the June 9 launch of the international Aquarius/SAC-D observatory. The mission's primary instrument, Aquarius, will study interactions between ocean circulation, the water cycle and climate by measuring ocean surface salinity. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Engineers at Vandenberg Air Force Base in California are performing final tests before mating Aquarius/SAC-D to its Delta II rocket. The mission is a collaboration between <a href="http://nasa-information.blogspot.com/">NASA</a> and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE), with participation from Brazil, Canada, France and Italy. SAC stands for Satelite de Applicaciones Cientificas. Aquarius was built by <a href="http://nasa-information.blogspot.com/">NASA</a>'s Jet Propulsion Laboratory in Pasadena, Calif., and the agency's Goddard Space Flight Center in Greenbelt, Md. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> In addition to Aquarius, the observatory carries seven other instruments that will collect environmental data for a wide range of applications, including studies of natural hazards, air quality, land processes and epidemiology. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> The mission will make <a href="http://nasa-information.blogspot.com/">NASA</a>'s first space observations of the concentration of dissolved salt at the ocean surface. Aquarius' observations will reveal how salinity variations influence ocean circulation, trace the path of freshwater around our planet, and help drive Earth's climate. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">The ocean surface constantly exchanges water and heat with Earth's atmosphere. Approximately 80 percent of the global water cycle that moves freshwater from the ocean to the atmosphere to the land and back to the ocean happens over the ocean. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Salinity plays a key role in these exchanges. By tracking changes in ocean surface salinity, Aquarius will monitor variations in the water cycle caused by evaporation and precipitation over the ocean, river runoff, and the freezing and melting of sea ice. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Salinity also makes seawater denser, causing it to sink, where it becomes part of deep, interconnected ocean currents. This deep ocean "conveyor belt" moves water masses and heat from the tropics to the polar regions, helping to regulate Earth's climate. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> "Salinity is the glue that bonds two major components of Earth's complex climate system: ocean circulation and the global water cycle," said Aquarius Principal Investigator Gary Lagerloef of Earth & Space Research in Seattle. "Aquarius will map global variations in salinity in unprecedented detail, leading to new discoveries that will improve our ability to predict future climate." </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Aquarius will measure salinity by sensing microwave emissions from the water's surface with a radiometer instrument. These emissions can be used to indicate the saltiness of the surface water, after accounting for other environmental factors. Salinity levels in the open ocean vary by only about five parts per thousand, and small changes are important. Aquarius uses advanced technologies to detect changes in salinity as small as about two parts per 10,000, equivalent to a pinch (about one-eighth of a teaspoon) of salt in a gallon of water. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> Aquarius will map the entire open ocean every seven days for at least three years from 408 miles (657 kilometers) above Earth. Its measurements will produce monthly estimates of ocean surface salinity with a spatial resolution of 93 miles (150 kilometers). The data will reveal how salinity changes over time and from one part of the ocean to another. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> The Aquarius/SAC-D mission continues NASA and CONAE's 17-year partnership. NASA provided launch vehicles and operations for three SAC satellite missions and science instruments for two. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> JPL will manage Aquarius through its commissioning phase and archive mission data. Goddard will manage Aquarius mission operations and process science data. <a href="http://nasa-information.blogspot.com/">NASA</a>'s Launch Services Program at the agency's Kennedy Space Center in Florida is managing the launch. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />
</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> CONAE is providing the SAC-D spacecraft, an optical camera, a thermal camera in collaboration with Canada, a microwave radiometer,; sensors from various Argentine institutions and the mission operations center there. France and Italy are contributing instruments. </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"><br />

</div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;">The Alpha Magnetic Spectrometer, or AMS, was carried into orbit on STS-134 on a mission to the <a href="http://nasa-information.blogspot.com/">International Space Station</a>. While it may sound like just another instrument, in actuality it is the largest scientific collaboration to use the laboratory! This investigation is sponsored by the United States Department of Energy and made possible by funding from 16 different nations. Led by Nobel Laureate Professor Samuel Ting, more than 600 physicists from around the globe will be able to participate in the data generated from this particle physics detector. <br />
<br />
According to Trent Martin, AMS project manager for NASA, "This type of collaboration is starting to become more common in the space science community, but AMS is by far the most diversely funded space based science detector ever built. This is the type of collaboration that NASA hopes the ISS National Laboratory will help foster in the space scientific community." <br />
<br />
The mission, to seek out answers to the mysteries of antimatter, dark matter, and cosmic ray propagation in the universe, is only part of the story. To fully understand where the science is going, you have to look at <a href="http://www.ams02.org/timeline-2/"></a> </div><div style="font-family: Arial,Helvetica,sans-serif; text-align: justify;"> NASA efforts with AMS began in 1994, when NASA's Johnson Space Center in Houston, Texas, conducted a feasibility study to see if such a delicate instrument could even fly in space and still produce usable data. <br />
<br />
Ken Bollweg, AMS deputy project manager for <a href="http://nasa-information.blogspot.com/">NASA</a>, mentions the challenges that needed to be overcome for the hazardous environment of space. "The detectors used in these types of experiments are typically used in an underground environment where the temperature doesn’t change more than two degrees from winter to summer and the bedrock hasn't moved in millennia," comments Bollweg. "Reviews of the detectors and their operating requirements indicated that it would be very challenging to adapt this technology to space -- but possible nonetheless." <br />
<br />
Work on AMS integration and interface hardware began in earnest upon approval in 1995. One of the first understandings <a href="http://nasa-information.blogspot.com/">NASA</a> needed to reach with the AMS Collaboration was the limitations of mass, size and power. For instance, the AMS Collaboration considered the AMS permanent magnet lightweight at approximately 2 tons, given that similar electromagnets on Earth weigh about 10,000 tons. <br />
<br />
Working together, NASA and the AMS Collaboration developed a two-part plan to enable the mass requirements. The Unique Support Structure or USS-01 completed in 1997 and was launched with STS-91 in June of 1998. It carried a 9,197 lb engineering evaluation version of AMS. With the successful STS-91 mission and some extra time, since it was clear that the station would not be ready to host AMS in 2001, the scientists decided to make a few improvements. Plans for the AMS grew to be more complex, including the upgrade to a more powerful cryogenic superconducting superfluid helium-cooled magnet. These changes increased the projected weight for AMS to 15,251 lb, making it necessary to test a second support structure, called USS-02. <br />
<br />
Determining a way to communicate the data from AMS to the ground was another important element of the undertaking. A digital data recorder system was developed and used during the STS-91 mission to capture data for the AMS Collaboration. Even though this was a preliminary effort to the overall AMS goal, the resulting data led to improved measurement sensitivity. <br />
<br />
Several years passed as engineers continued working on procedures, certification requirements, and entered into the testing phases of development. In December 2001 <a href="http://nasa-information.blogspot.com/">NASA </a>flew a prototype synchrotron radiation detector with STS-108. This flight test clarified performance of the detector for the AMS. The enhanced complexity of the AMS also meant an increase in data channels from close to 70,000 to over 300,000. In response, NASA developed a new digital data recorder system, which launched on STS-133 in February 2011. This enabled a trial run of the recorder system in preparation for the actual launch of AMS with STS-134. <br />
<br />
With the announcement that the space station would continue to operate through 2020, the AMS Collaboration swapped out the current cryogenic magnet with a permanent magnet, which would have an infinite life. The entire AMS was taken apart, the magnets exchanged, and put back together for testing. From concept to implementation, this only took seven months to extend the potential life of the AMS investigation. <br />
<br />
Martin commends the efforts of the many NASA and contractor personnel who made significant contributions to the completion of the AMS investigation. These individuals will continue to support AMS while it is on its mission in orbit to gather valuable data. Martin notes in particular the support of <a href="http://nasa-information.blogspot.com/">NASA</a>'s Bill Gerstenmaier, associate administrator for space operations. "[He was] critical to AMS's success, especially while AMS was off the space shuttle and space station manifests after the Columbia accident," says Martin. "He saw to it that Advanced Projects Office personnel were able to continue with the integration and certification tasks and personally visited AMS at various stages of development and testing." <br />
<br />
The AMS will be the most advanced charge particle detector flown in space, increasing global knowledge of antimatter and dark matter and providing a powerful tool to physicists. The investigation will enable the discipline of modern physics to grow as scientists seek answers to the origins of our universe. <br />

Or GPS? Or tablet computers? Kind of hard, isn't it? Air traffic management researchers feel the same way about life before the Future ATM (Air Traffic Management) Concepts Evaluation Tool, or FACET. <br />
<br />
FACET is a computer program developed by <a href="http://nasa-information.blogspot.com/">NASA</a> that generates simulations for managing air traffic scenarios. It provides a "big picture" view of what's happening in the skies overhead. For any given moment in time, it can show thousands of aircraft swarming through our national airspace. With each aircraft represented as a tiny icon, a FACET simulation can look like an "ant farm in the sky," with aircraft clustering around major airports like ants targeting a drop of peanut butter. You may have seen video generated from FACET on the morning news during air travel outlook reports. <br />
<br />
Recently, the creators of this simulation software at NASA's Ames Research Center in California won <a href="http://nasa-information.blogspot.com/">NASA</a>'s 2010 Government Invention of the Year. The award, presented by <a href="http://nasa-information.blogspot.com/">NASA</a>'s Inventions and Contributions Board, is given to inventions that have made a significant contribution to NASA's goals and to broader communities; in this case, the aeronautics community. Nominations are rated on use, creativity, benefits to the community, and overall significance to humankind. <br />
<br />

<br />
"As the world's population grows and air travel demand increases, our airspace will become more crowded," said Banavar Sridhar, <a href="http://nasa-information.blogspot.com/">NASA</a> senior scientist for Air Transportation Systems. "FACET helps air traffic management researchers find ways to increase airspace capacity and establish more efficient routes with the least impact on the environment, thereby saving fuel and minimizing emissions." <br />
<br />
One of the best things about FACET is that it doesn't need supercomputers to run, even when asked to crunch data from thousands of flight plans. The software can operate on a single computer, which was a big leap forward that really helps researchers. FACET can model current traffic patterns to see where improvements could be made, or model entirely new patterns that result from new flight operations techniques, like new merging and spacing rules, weather avoidance techniques, or approach patterns into airports. <br />
<br />
How does it work? FACET uses aircraft performance profiles, airspace models, weather data, and flight schedules to model trajectories for the climb, cruise, and descent phases of flight for each type of aircraft. Then a graphical interface displays the traffic patterns in two and three dimensions, under various current and projected conditions for specific airspace regions or over the entire continental United States. You'll see examples of all of these different models in the video linked from this page. <br />
<br />
According to FACET team members, the software has become a valuable tool for Federal Aviation Administration traffic flow managers and commercial airline dispatchers. They use FACET technology to do real-time operations planning by combining live air traffic data from FAA radar systems and weather data from the National Weather Service to create a real-time big picture of what's happening in the air. With that information, airspace system operators can reroute flights around congested airspace and severe weather to maintain safety and minimize delay. <br />
<br />
This is one big picture that's having a big impact on air travel. <br />
